the arch looked like at the tennessee beach at tennessee cove for decades. for many years it's also been a favorite spot for pictures. but on december 29th. a graduate student at the institute of technology was on the beach taking pictures when all of a sudden that arch came tumbling down. the graduate student and his geologist father said the noise was so loud it also blocked out the sounds of the waves. >>> it starts way up here and you see the curser this red line. when the systems come like this they come up over the cold and down over the land like this they don't have a chance to warm up. a lot of times these systems worm up but this one coming down is going to be a cold one. cold systems carry little moisture with them. so we're not expecting rain or precipitation from it. this one will see a few sprinkles but not a lot. maybe .01, .1 at the most. fog is going to be a problem tomorrow morning. as you head off to work get going around town, early morning the fog will be in the east bay and south bay valley. the dewpoints are running right about where the temperatures are right now.
